What is a Technical Writer?!

This question popped in my head after one of my kids asked me the main job of what I do. So, it reminded me of the exchange between Dracula and Richter Belmont at the beginning of Castlevania: Symphony of the Night.

Let me pick up the part of this exchange to parody Dracula:

       "What is a technical writer?!" 

       (Hear the laptop casted from my hand             and crash to the ground)

      "A herder of cats with a smattering of               writing?!"

       "But enough words! Let's document!"
